Introduction. Machine Language For Beginners. New defenses for automated SQL injection attacks.
Recently, analysts at the SANS Institute's Internet Storm Center discovered a tool that automates the process of finding and exploiting websites vulnerable to SQL injections. The automation illustrates the increasingly popular technique of using parts of legitimate sites to host and deliver malware. In this tip, let's take a look at SQL injection attacks and examine how to find, isolate and address the malicious pages of an otherwise safe website. SQL injection attacks of the past SQL injection attacks are nothing new.
In a high-profile 2003 case, for example, apparel company Guess Inc. suffered a SQL injection attack on its website, which resulted in a security breach and a government-led legal settlement.

When a set of data is locked by a user, no other users can modify that same set of data until the first user finishes modifying the data and relinquishes the lock. There are exceptions, but let’s not go there. Some databases, SQL Server included, use locks to prevent users from seeing uncommitted modifications. In these systems if UserA is modifying some set of data, then UserB and all the rest of the users must wait until UserA is done modifying that data before they can even get a shot at reading the data, let alone modifying it. Databases place locks at all levels of their physical hierarchies: rows, pages (typically a few KB of rows), extents (typically a few pages), entire tables, and entire databases.

There are many ways to plan an effective Link Strategy and in this post we will try to understand how each method works.
